What's your opinion on this?

scary!!!

...In other words, you're trying to tell me I'm a monster in a "sneaky-ish way"?

And they do not live among us, they live within us.

i don't think so

glad to know

True in most cases. Real monster monsters do not exist, but bad people monsters may hide under the 침대 또는 in the closet if 당신 come 집 when they are robbing your 집 (that is if they could fit under the bed).

Rather ridiculous it is just an active imagination.
